Larry Lopez of Los Alamos Technical Associates screens core samples for volatile organic compounds using a photoionization detector at Technical Area 50 MDA C. The Environmental Stewardship (ENV) Division is investigating material disposal area "C" for remediation. Investigations include drilling boreholes around the site boundaries and measuring for radioactivity and volatile organic compounds. MDA C was established in May 1948 and served as the main Laboratory disposal facility for approximately 20 years. The site covers about 12 acres. The inventory at TA-50 MDA C is distributed among 108 shafts and seven pits formerly used for burial of waste.
